1. Catching an NPR executive bashing Tea PartiersO'Keefe orchestrated this week's video ambush of NPR executive Ron Schiller, who was caught on tape lambasting Tea Party conservatives as "seriously racist" people. Two "undercover O'Keefe lackeys" posed as representatives of a Muslim education charity, and reportedly offered to give NPR a $5 million donation. The dust still hasn't settled, but NPR chief executive Vivian Schiller (no relation) has already resigned from her post. O'Keefe's "fraternity-like tactics" went too far this time, says Leslie Marshall at U.S. News & World Report. "Taping anyone without their consent is illegal," and I think Ron Schiller should sue "big brother O'Keefe."

3. Trying to tamper with a Democratic senator's phoneNot all of O'Keefe's pranks have been successful. The activist was arrested in January 2010 after breaking into the New Orleans office of Sen. Mary Landrieu (D-La.), in an apparent attempt to interfere with the building's telephone lines. O'Keefe and three accomplices were later given three years probation and a fine for entering federal property under false pretenses. Some of O'Keefe's former fans expressed distaste at his tactics. Glenn Beck said he had entered "Watergate territory."

4. Attempting to humiliate CNNUndeterred by his arrest in Louisiana, O'Keefe continued to try to embarrass those whom he sees as shills for the left. In September 2010, CNN revealed O'Keefe was plotting to embarrass CNN correspondent Abbie Boudreau by luring her onto a boat filled with "sexually explicit props" and filming her reaction. CNN smelled a rat, and reported O'Keefe's involvement with the failed stunt. This time, even the conservative blogosphere reacted with disdain. Exposing media bias with a video camera is one thing, said Caleb Howe at RedState, but "luring a lone female reporter to a remote location" in an attempt to cause her "discomfort and fear"? That's just "despicable."

5. Exposing teachers unions in New JerseyO'Keefe returned at the end of 2010 with a secret video filmed in New Jersey, which purported to show unionized teachers admitting how hard it was to fire a tenured teacher. In one of the tapes, teacher Alissa Ploshnick says one of her colleagues called a pupil a "nigger" without being canned. Still, the video, said Bob Braun at the New Jersey Star-Ledger, was a "phony expose of nothing but the cynicism of ideologically driven pseudo-journalists."
